hey guys i bought a bubble coral on a piece of LR. after the first night something made what looks exaclty like a spiders web between the rock and the glass, i removed it and the next night its was back up again. does anyone whats making it? cheers

There is a snail i forgot the exact name but if u look for somthing brown or black you will find him. He wont move and hes harmless that spider web is his way of capturing food from the water colum. Only problem iv seen with him is they will multiply which is what they are doing in my tank now. But from what iv seen they are harmless.
